AUTOMOBILE-WHEEL.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed July 26, 1907. Serial No. 385,698.

To all whom it may concern:

Be it known that I, OLE A. HAMRE, a citizen. of the United States ofAmerica, residing at Arriba, in the county of Lincoln and State ofColorado, have invented new and useful Improvements in AutomobileWheels,of which the following is a specifieatlon.

This invention relates to automobile wheels, and one of the principalobjects of the same is to improve the construction of that class ofresilient cushioned tire wheels which are practically non-puncturableand which yield to the motions of the vehicle.

Another object of the invention is to improve the construction ofcushion-tire automobile wheels in general.

These and other objects may be attained by means of the constructionillustrated in the accoin mnying drawing, in which Figure l is a sideelevation of an automobile wheel made in accordance with my invention.Fig. 2 is a side elevation and partial section of a portion of the rimof the wheel. Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Referring to the drawing for a more particular description of myinvention, the numeral 1 designates the hub of the wheel, 2 are thespokes and 3 is the rim, these parts being made either of wood or metaland of any required construction to suit the character of vehicles withwhich the wheel is to be used. Secured to the rim 3 upon the peripherythereof is a rubber annular channel tread portion 6, which may be of anyre quired cross sectional contour, is provided with upwardly projectingflanges 7 disposed inside the lips or flanges 5. Secured to the treadportion 6 of the tire, at suitable intervals, and in parallel relationare shafts or rods 8, said rods passing through the annular channelmember 4 and through the rim*3 and extending between the spokes 2 of thewheel. The rods 8 are each provided with a collar 9 The I forming a stopfor the encircling springs 10 which surround the rods 8. A nipple 11. issecured in an aperture in the rim 3 said nip ple having a threaded outerportion to which a cap 12 is secured said cap having a partition 13therein through .which the upper end of the rod 8 projects. The springs10 bear at inner ends against the partition 13 as shown moreparticularly in Fig. 3.

From the foregoing it will be obvious that a tire made in accordancewith my invention will yield in passing over obstacles or upon roughroads and that the device is of simple construction and entirelyobviates the annoyance of punctured tires. The springs are entirelycovered and access may be had to any of the springs by removing the cap12.

Having thus described the invention, what I claim is:

A wheel comprising a hub, spokes and a rim, a tire engaged with said riman annular channel member secured to the rim, said rim and said channelmember having alining passages formed therein located between the saidspokes, nipples upon the rim in line with the said passages, capsadjustably secured to the nipples, each cap having an aperturedpartition, rods slidably mounted in the passages formed in the channelmember and in the rim, said rods having their outer ends secured to thetire and having their other ends slidably mounted in the aperturesformed in the partitions, stop collars secured to the rods, and helicalsprings coiled about the rods and confined between the collars andbetween the partitions in the said caps, the said caps being mounted formovement upon the nipples so that the tension of the springs within thecaps may be regulated.

In testimony whereof, I affix my signature in presence of two witnesses.

OLE A. HAMRE.
